Brief Answer:
probably not

Detailed Answer:
Hello,

More commonly than not, sore throat and white spots on the tonsils are caused by viral infections (not streptococcus that is). This particularly so when the patient also has runny nose/congestion and/or cough. In favor of streptococcus are the following signs/symptoms or factors:
- high fever
- enlarged and painful cervical lymph nodes
- age (adults are less likely to get streptococcus)

Please note that the appearance of the tonsils is not diagnostic and cannot distinguish between viral and bacterial causes. I must add that in many cases streptococcus causes extensive white patches on the tonsils. Although the lack of extensive white patches does not exclude streptococcus, it is usually suggestive of other causes.

It's because we can't clinically distinguish between the various causes or tonsilitis that a strep-test is required in most cases. The strep-test can identify the presence of streptococcus in the throat. Therefore this is the recommended course of action for someone with a sore throat and white spots on the tonsils. If the strep-test is positive then antibiotics should be prescribed. Otherwise antibiotics can be avoided.

I hope I've answered your question. Please let me know if you need further assistance.

Regards.
